How Much Of Your Risk Sits Inside Someone Else's Company?
Your availability, your compliance posture and your breach exposure are all partly determined by vendors you do not control. A subprocessor incident becomes your incident, your notification obligation, and your customer's question.
Assessment happens once, at purchase, and never again. Vendors get acquired, change subprocessors, and drift in security posture — the risk you signed up for is rarely the risk you are carrying two years later.
Questions CTOs ask
- What should a vendor risk assessment cover?
- A thorough vendor risk assessment evaluates five domains: security posture (certifications, vulnerability management, incident history), compliance alignment (regulatory requirements relevant to your industry), financial stability (revenue trends, funding status, customer concentration), operational risk (SLA track record, disaster recovery, key-person dependencies), and contractual protections (data ownership, exit clauses, liability caps). Weight each domain based on how critical the vendor is to your operations.
- How often should vendor risk assessments be updated?
- Critical vendors (those handling sensitive data or supporting core business functions) should be reassessed annually with continuous monitoring of security posture changes. Standard vendors warrant biennial reviews. Trigger-based reassessments should occur after any vendor security breach, major acquisition, leadership change, or significant service degradation. Many organizations use automated vendor risk monitoring platforms to supplement periodic manual reviews.
